Sensory behaviors are among the most visible features of autism. They reflect differences in how the nervous system processes sensory input and can range from mild preferences to intense needs that significantly affect daily life.

Sensory Seeking Behaviors

Some autistic individuals actively seek sensory input. This may look like crashing into furniture or people, seeking tight squeezes, spinning or swinging for extended periods, craving strong flavors or smells, making loud vocalizations, or visually focusing on spinning objects or bright lights. These individuals need more sensory input than their environment naturally provides.

Sensory Avoiding Behaviors

Others avoid sensory input because it feels overwhelming. Covering ears at everyday sounds, refusing certain clothing textures, avoiding eye contact due to visual sensitivity, gagging at food textures or smells, and withdrawal from crowded spaces are all sensory avoidance behaviors. These individuals are receiving too much sensory input from their environment.

Mixed Profiles

Many autistic individuals have mixed sensory profiles, seeking input in some sensory channels while avoiding it in others. A child might crave deep pressure touch while being extremely sensitive to light sounds. Understanding the individual’s complete sensory profile is essential for effective support.

Supporting Sensory Needs

A sensory diet created by an occupational therapist provides planned sensory activities throughout the day. ABA therapy incorporates sensory accommodations into treatment and teaches the individual to self-regulate using appropriate sensory strategies. Environmental modifications at home and school reduce sensory triggers while providing access to desired sensory input.
